' ACTUATING MECHANISM FOR TURN-TABLE PIPE-CASTING APPARATUS.

Specification of Letters Patent.

fatented Sept. 15, 1908.

Application filed March 27, 1908. Serial No. 423,725.

To all whom it may concern:

Be it known that I, EDGAR ALAN CUs'rERf a citizen of the United States, residing at the city of Philadelphia, in-the county of Phil- 'adelphia and State of Pennsylvania, have invented certain new and useful Improvements in Actuating Mechanism for Turn-Table Pipe-Casting Apparatus, of which the following is a specification.

M invention has relation to an actuating mec anism for the turntable of a pipe casting apparatus es ecially such as has been described and cl irned in the United States Letters Patent N 0. 870,817 granted to me under date of November 12th, 1907; and in such connection it relates more particularly to the constructive arrangement of means for imparting to a turntable'a step-by-step rotary movement in one direction thereof.

The principal objects of my invention are first, to arrange the actuating mechanism so as to rotate the turntable from two diametrically opposite points to reduce strain incidental to movement of structures of the tumtable; second, to provide a turntable with blocks at predetermined distances apart and to so' arrange the same in the table as to permit the actuating means on the one hand to move the blocks out of operative position and on the other hand to permit the same to ative' position, whereof the blocks form a connecting means between the turntable and the actuating mechanism thereof; third, to provide theactuating means with a cam or throw portion for moving the blocks out of their normallyoperative position; and fourth, to provide asactuating means a cylinder .which by being movably arranged on a fixed piston and. rod serves to su port the cams and in conjunction therewit :and blocks to tary movement in onedirection thereo The nature and scope of my present mvention will be more fully understood from the following description taken in connection with the accom anying drawings forming part hereof, in w ich Figure 1 is a view, illustrating in top or plan, a portion of a turntable, the molds carried b the same, a ortion oftrack supporting tie table, and actuating mechanism therefor. Fig. 2 1s a view enlarged, illustrating partly in sectionand elev'ation, a portion of the turnta and preferably consisting of I-beams 5, connected with each other by cross-pieces 6,

having formed integral therewith, bearings 8, for the shafts 9, of traction-wheels 10, engaging rails 11 supported in the present instance by carriers 12, embedded in a base 14,

of concrete or-othersuitable material. To the I-beams 5, are secured outwardly extendin brackets 15, forming in conjunction with t e I-beams 5, and cross pieces '6, a

frame for supporting a plate 16, annular in outline. Upon the plate 16, are placed at predetermined distances apart permanent molds 18, preferably of the 'type described and shown in Letters Patent granted to me under date of May 12th, 1908, under the No.

887,070, the parting line of which is arranged at an angle to the horizontal and having pour-holes 20, arranged in the cope 19 at the upper end of the parting line, as shown 1n Figs. 1 and 2. Each of the crossieees 6, of

tegral the table 4, is provided, preferab ym therewith, with a pocket or chain which 'is loosely arranged a bolt or block 22, extending through andbeyond thepocket r 21, in

21 and held in this normal or operative position b the head 23, resting in this position on a s oulder 24, of the pocket 21. As shown in Fig.1, on the base 14, and at two diametrically opposite oints intermedi ate of the rails 11 and direct ybelow the bolts 22, of the turntable 4, are cylinders 25, supported by abase 26, having a range of sliding movement in a bed or guide plate 28', suitably secured to the base 14. Each of the cylinders 25, is provided with a piston 29,

held in a fixed position by means of a piston rod 30, which passes through stufiing boxes 31, of the cylinder 25, and is removably secured at the respective outer ends in guideplates 28, by means of brackets 32, preferably formed integral with the plates 28. Fluid le, molds car- 55 'ried thereby, a cylinder sliding on a fixed under pressure from a suitable source, not

shown, is introduced by means of pipes 33,

into each of the c linders 2 5, alternately on o posite sides '0 the pistons 29 thereof,

w ereby the gylinders are reciprocated on the pistons an piston-'rods'30, in the guideplates 28'. This reci rocatory movement is utilized to move the locks orbolts 22, alternately into an inoperative position and to impart to the turntable 4, with the aid of the blocks or bolts 22, a step-by-step rotary movement of the table in onedirection b the following preferredmechahismz-Eac of the cylinders is provided at the upper portion with a projection 34, terminating substantially in the central portion thereof, and having an inclined portion 35, serving as a cam. When the cylinders 25, are moved gagement wit tab e.

tive position in front of the projection 34,. now forming in conjunction therewith a between the c linders and turnhen the cylin ers25, are moved cou lin forward from left to right in Fig. 2, the ro- 'ection 34, by abutting a ainst the bloc of olt 22, directly in front 0% the same shift the table forwards and by such movement bring the molds 18, carried by the table successively into 'a metal receiving position with respect to a pouring mechanism preferably of the type described and shown inan application for a patent filed b me under date of March 14th, 1908, under erial No. 421,054. As the turntable 4, is simultaneously actuated by the cylinders 25, arranged diametrically opposite to each other the strain on the said mold structures thereof, incidental to such movements of the table is greatly lessened and uniformly. distributed over the same. In order to reduce wear on the projection 34, the same as to the actuating face 36, is provided with a removable bearingplate 38.

Having thus described the 'nature and objects of my invention what I claim as new and desire to-secure by Letters Patent is 1. In a mechanism of the character described, a table carrying molds, means movably arranged in the table and normall projectin therefrom, and means reciproca l5 arjunction t range below the table and having means for raisinglthe movable means and in conerewith adapted to impart to the table a step-by-ste rotary movement of the table in one direction thereof.

. 2 In ,a mechanism of the. character described, a table can ing molds and actuating means for said tab e, said actuating means, consisting of bloeks'oi: bolts movably arranged in said table and normall projecting therefrom, and a movable cylin or having a cam for raising said blocks or bolts into an inoperative (position, when moved in one direction an imparting in conjunction with the same to saidtable a step-by-step rotary movement, when moying in an opposite direction.

3. In a mechanism of the characterdes scribed, a table carrying molds and combined coupling and actuating means, said means consisting of blocks forming one member of the couplinlg movably arranged in said table and norma y occupying1 an o erativ'e position b projecting from t 0 .tab e and a cylinder avin a projection forming the other member 0 the coupling connecting thev table with said cylinder, the projection of said cylinder ada ted when mo'ved in one direction to raise t e blocks into an inoperative position and when move -in anopposite osition to impart in conjunction with said blocks to the table a step-by-step rotary movement thereof.
